SPECIFICATION forming part of Letters :Patenta No. 559,196, dated Aprl 28, 1896. `.l-ipplieation filed September 19 18951. Serial No. 563,047. (No model.)

g following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of" reference marked thereon, which form part` of this specification. y

This invention is an improvement in pneumatic stackers especially designed for cloverhulling machines; and its object is to divide the waste products of the machine-such as straw-stalks, chaf, dust, &c-into two parts and carry them out of` the machine by the direct suction of fans without other auxiliary mechanical discharge devices, the two streans of waste products bei-ng reunited outside the machine in a common dischargcspout. 4 i

The invention therefore consistsin the novel and improved constructions and` combinations of parts set forth in the claims, and the accompanying drawings illustrate a useful form of the apparatus. i

In said drawings, Figure 1 is a side elevation of the rear portion of a hulling-machine embodying the invention. Fig. 2 is a longi- Fig. 3 is a transverse vertical section on line 3 3, Fig. 2. Fig. 4: is a rear end View. Fig. 5 is a detail view of the divider and a fan.

The huller is of usual Construction or other preferred form, and has a series of Vibrating screens A A' A upon which the straw-stalks, (330., are carried forward to the dischargechamber B at the rear end of the machin e, the seed falling successively through the screens and finally onto a sieve a, through which the seed pass to the discharge, while the ohaff and light impurities are driven up (by a blast of air from a fan O in a casing below the screen) over a partition a' into chamber B.

The bottom of chamber B is hopper-shaped, and extending transversely through the chamber is a shaft D, on which are fixed two disks D', one at each side of the chamber or each end of the hopper-bottomthereof, and on the inner faces of said disks are wedge-shaped blades D constituting fans, said fans being inclosed in casing E, each having an eye on its inner side communicating with chamber B, and a bottom lateral discharge-pipe E', coniinunicating with one of the bifurcations F of a pipe F, attached to the rear end of the ma chine. To the upper end of pipeF is hinged discharge-spout f. When in position for use, as indieated in Fig. 1, pipe F is upheld by a brace-rod F as shown. WVhen on the road, pipe F is turned up against the rear end of machine and spout f turned down on top thereof, as indicated in Fig. 2.

i 011 shaft D, intermediate of the fans D', are secured two cones d, between the bases of which (which abut at the center of the shaft) is secured a serrated disk d'. Obviously these parts night be formed in one, if desired.

The cones and disk d' constitute what I term the divider, and are not designed to cut but merely to separate the straw and waste material entering chanber B into two parts, one half of which is thrown to one side and is taken in by one of the fans and the other half is thrown to the other side and then is taken up by that fan. The blast froni these two fans, together With the material with which it is ladened, are passed through the branched pipe F, and the two currents j'oin each other and i passing through spout fare discharged on the stack in the usual manner.

The object of the double cone is not merely to start the dividing material to the respective fans on the sides of the machine, but principally to prevent the straw from winding about the shaft D, the cones being of such diameter as will prevent the straw from engaging the shaft and being Wound up around it. Of course the straw does incidentally slide off to one side or the other from these cones until it is caught by the suction from the fans, When it is drawn in through the faneyes and discharged.

A curved shield I is placed beside and partly over the divider at the side next screen a, so as to prevent the divider throwin g or blowing material back over partition a'.

a The blast from fan O passes up through sieve a and serves to separate the light chaff from the seed. 4 This chaff is then blown through opening b into the receiVing-chamber and is taken in by the fan to which it is nearest, and 'the suction of said fan by the ICO aid of this dividing-cone takes the finer refuse and dust from the interior of the machine and discharges them in the open air on the stack. The suction of the fans may be regulated by narrowing the throat b or by admitting air in the receiving-chamber, as usual.

The straw falls ahead of the defiector onto the divider, by which it is separated into two parts.

The particular features of this machine are the dispensing with any mechanical feeder or stoker for the discharge of the waste products, the dividing of such products, and the separate withdrawal of the divided products directly by the suction of the fans.

Shaft D may be driven by a belt 0 and pulleys 61 c' from the shaft c of fan C, the latter being driven by the usual means. (Not shown.)

The rear end N of the main frame is hin ged at n to the top bar and may be turned up When the spout is fully lowered, allowing access to the ch ambel' B for cleaning or repairs.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

1. In a clover-huller the combination of the discharge-chamber, and the fans on opposite sides thereof adapted to divde material entering` the chamber by their suction into two portions and to eject said portions from the chamber, with a divider for dividing the products entering the chamber into two portions, and deflecting a part to each fan, for the purpose and substantially as described.

2. The combination of the dischargechanber, the hopper thei-ein, the transverse shaft, the separate exhaust-fans on said shaft at opposite sides of the chamber, and the fan-casin gs communicating at center with said chamber and having separate discharge-pipes leading out of the chamber; with means for di- Viding the waste products entering` the chamber into two parts and directing one part to each fan, substantially as described.

The combination of the discharge-chamber, the suction-fans on opposite sides thereof, and separate discharge-pipes from the fancasings; with the rotary double conical divider intermediate of the fans, substantially as described.

4. The combination of the discharge-chamber, the suction-fans on opposite sidesthereof, and separate discharge-pipes from the fancasings; with the rotary double conical di- Vider intermediate the fans, and a common discharge-spont eXterior to the dischargei chanber communicating with both fans, substantially as described.

5. 'The combination in a thrashin g-machine, of a discharge-chamber, apair of suction-fans therein, separate dischargepipes from the fan-casings, substantially as described, and a common discharge-spout with which said pipes connect; with a rotary divider in said chamber, and a shield beside the divider, substantially as described.

G. The combination of the discharge-chamber, the suction-fans on opposite sides thereof adapted to wthdraw material therefrom by suction, and separate discharge-pipes from the fan-casings; with the rotary divider intermediate the fans, and a shield partly over the divider at the inlet side of the chamber, substantially as described.

7. The combination of the discharge-chamber, the hopper therein, the transverse shaft, the fans on said shaft at opposite sides of the chamber, and the fan-casings communicating at center With said chamber and having separate discharge-pi pes leading out of the chamber; With the double cones on said shaft intermediate the fans, and the divider or serrated disk between the cones, substantially as and for the purpose described.

8. The combination of the discl'arge-chamber, the hopper therein, the transverse shaft, the exhaust-fans on said shaft at oppositc sides of the chamber, and the fan-casings communicating at center With said chanber and having` separate discharge-pipes leading outof the chamber; with means for dividing the waste products entering the' chamber and directing part to each fan, a bifurcated discharge-pipe hinged to the discharge-pipe of the fans, and the spout hinged to said bifurcated pipe, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
